DallaSanta, K., C. Orbe, D. Rind, L. Nazarenko, and J. Jonas, 2021: Response of the Quasi-Biennial Oscillation to historical volcanic eruptions. Geophys. Res. Lett., 48, no. 20, e2021GL095412, doi:10.1029/2021GL095412.

The impact of volcanic eruptions on surface climate is well-appreciated, but their in situ impact on the Quasi-Biennial Oscillation (QBO) has received comparatively little attention. This study examines the QBO responses to Krakatoa and Pinatubo using five configurations of the NASA Goddard Institute for Space Studies (GISS) Model E2.2 and MERRA-2 reanalysis. A dynamically consistent response is found in terms of static stability, zonal wind, and upwelling. Eruptions are found to bias the QBO towards a westerly phase, such that the period response is a function of its initial phase, with an additional contribution from gravity wave momentum flux due to convection. The QBO does not have a clear amplitude response to an eruption, based on these simulations. The underlying mechanisms appear not to be influenced to first-order by interactive composition, sea surface temperatures, or long-term trends in CO2 and ozone-depleting substances. %AB .
